- This invention relates to a combined brush with combs, of the type wherein these two elements are utilized simultaneously and in cooperation, for improved and efficient combing and brushing of the hair, and its principal object is to provide a simplified, eflicient, conveniently operable, and improved article for this purpose.

Another object is to provide such article with improved means for mounting the combs thereon and demounting them therefrom, to permit efficient and convenient cleansing or renewal of the combs.

Another object is to provide such article with improved means for positively locking said comics in requisite place when in mounted position.

Other objects and advantages will hereinafter appear.

In the accompanying drawing Fig. 1 is a plan view of the article, with the brush partially broken away, showing the combs in operative position.

Fig. 2 is a transverse-sectional View, in an enlarged scale, of the article shown in Fig. 1.

Fig. 3 is a view similar to Fig. 2, but showing the combs in inoperative position.

Fig. 4 is a longitudinal cross-sectional View, showing a detail of the mechanism of this article.

Fig. 5 is a plan view, in a reduced scale, showing a modification of the invention.

The article I comprises the usual body 2, a handle 3, and a brush 4 set in said body, the latter being provided with a channelled chamber 5 that extends clear therethrough from side to side 6 thereof, as shown in Fig. 3. Within the chamber 5 and along the longitudinal centre line thereof is located a shaft 1 which is rotatably mounted in a bearing 8 and in a nut 9 lodged in a recess l9. Said shaft carries a pair of gears II that mesh with racks l2 forming part of a framing l3 adapted to receive a comb l4, and the gears also mesh with upper racks l5 forming part of a framing l6 adapted to receive a comb l1. Upon rotation of shaft 1, therefore, in a clockwise direction as viewed in Fig. 3, the framings l3, l6 and the combs carried thereby are propelled within the chamber 5 toward the shaft to the concealed position shown in Fig. 3, while rotating the shaft backwardly projects the combs M, H outwardly to the operative position shown in Figs. 1, 2. The shaft '1 is manipulated by a knurled cylinder l8 fixedthereon, which cylinder is set in a recess !9 provided in the body 2 near its junction with the handle 3 and protrudes through the surfaces of the upper side .and underside of the body, as shown in Fig. 4. The racks l2, are preferably guided by channels 29 formed in the chamber 5, and so proportioned that when the combs l4, F! are moved fully to the inoperative position shown in Fig. 3 their terminals 2| abut against the channel-ends 22 to limit their motion 1938, Serial No. 225,508

in this direction, while moving the combs to operative position causes the rack-terminals 23 to abut against the channel-ends 24 to similarly limit the movement of the parts in an opposite direction. To further assure the limitation of movement of the combs and'the said parts, the cylinder I8 is mounted in its recess is to maintain the shaft '5 against longitudinal movement and the shaft-portion la and nut 9 are threaded and tapped, whereby rotation of the cylinder it in one direction causes the nut 9 to bind thereagainst and lock the shaft 1, Fig. 4, with the combs in inoperative position, while rotating the cylinder I8 oppositely causes the nut 9 to bind against the end 25 of recess In, which thereby locks the shaft 1 with the combs in the operative position shown in Fig. 1.

Each of the combs is insertable into and removable from its receiving framing I3 or IE, and is held therein by the dove-tailed configuration of the comb-back and the framing, Figs. 2, 3. The comb is inserted into the framing longitudinally through its end adjoining the rear end of the body 2, and when fully inserted the terminal 26 of the comb abuts against the ledge 2'! of the body 2 to limit and position the comb in requisite location in the framing. A trigger 28 slidable in a recess 29 formed in the body 2 and impelled by a spring 39 is normally projected outwardly from the body and is located against the rear end 3| of the comb, in which manner the latter is insured "against accidental withdrawal from its framing or dislocation. When it is desired to remove the comb for cleaning or renewal, the trigger is pressed back into its recess 29 and the comb may be then retracted or withdrawn from its framing.

According to the modification shown in Fig. 5, the shaft 1 extends from the body 2 clear through the brush-handle 3 and projects from the extremity 32 of the latter, whereat its terminal is formed as a knurled cylinder 33, similar to the cylinder l8. A collar 34 formed on the shaft 1 is seated in 'a registering recess 35 in the body 2 and maintains the shaft against longitudinal displacement. The shaft portion la adjacent to the cylinder 33 is threaded and carries a tapped square nut 36 which is slidable in a registering square recess 31 in the handle 3. Rotation of the shaft 1 in one direction, therefore, propels the nut 36 to bind against the cylinder 33 to lock the shaft, while reversing the rotation causes the nutto bind against the end 38 of recess 31 and locks the shaft against rotation in the opposite direction.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
